## Common questions

### How should I configure Docker CryptPad for a reverse proxy?

For Docker deployments, set httpUnsafeOrigin in config.js to your public IP or domain and port. Set httpAddress to 0.0.0.0 so the container is reachable through a reverse proxy.

### What should I keep after starting CryptPad for the first time?

Run node server and save the installation URL with the unique token. You need that link to finish setting up your instance.

### How does CryptPad handle usernames and passwords for accounts?

Registration and account access use cryptographic keys derived from the username and password. The server never needs to see either value.

### Why might CryptPad stop working in a browser?

Common issues are often caused by browsers or extensions that interfere with CryptPad's security features or disable basic browser functionality. Check the documentation's list of extensions.
